study on delayed graft function using paired kidneys

Conditions: Delayed Graft Function

Summary: the study is designed to evaluate the safety and efficacy of an intravenously administered drug in recipients of kidneys from cardiac death donors who are risk for developing delayed graft function.

renal transplantation is the most effective and cost-efficient form of renal replacement therapy for a burgeoning population that presents with end-stage renal disease. although organ donation has become a national priority, the gap between the number of patients awaiting a kidney versus the number of available kidneys continues to widen exponentially. in many countries within the european union, utilization of "donation after cardiac death" (dcd) kidneys is steadily increasing, expanding the donor pool by \> 50%. given the high incidence of cardiac deaths in the us, aggressive pursuit of the dcd kidney pool could potentially reduce waitlist periods to months, if not days. risk for delayed graft function (dgf) with the attendant risks for increased recipient morbidity, chronic allograft nephropathy and increased medical costs has however tempered dcd kidney utilization in this country. development of strategies that limit normothermic reperfusion injury, promote renal repair, reduce the incidence and/or duration of dgf and improve long-term outcome can greatly enhance acceptance and recruitment of dcd kidneys. the study is designed to evaluate the safety and efficacy of an intravenously administered drug in recipients of kidneys from dcd donors who are risk for developing dgf. this trial is unique in that it compares drug versus placebo outcome in kidney recipients from the same donor with direct evaluation of function (creatinine clearance) in the graft.
